RandomShuffle uses one random number generator to shuffle the numbers
produced by another to obliterate sequential correlations.
To initialize a RandomShuffle, pass it two RandomElements. The
first RandomElement is used to generate a table of random numbers
and the second is used to choose one from the table. An example of
usage is,

RandomElement markov=new RandomShuffle(new Ranecu(),new Ranmar(),32)

which would generate a deck of 32 numbers from RANECU and
use RANMAR to choose from the deck.
